IMPROVEMENT IN REMOVABLE TOPS FOR SHOW-CASES.

Specification forming part of Letters Patent No. 195,529, datedSeptember 25, 1877; application filed June 11, 1877.

To all whom may concern:

Be it known that I, THOMAS H. B. PARKS, of Arkadelphia, in the county ofClark and State of Arkansas, have invented a new and Improved Show-CaseSash, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a sectional front viewof my improved show-case sash; and Fig. 2, a vertical transverse sectionof the same on line a: at, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention is a detachable front or cover designed for application toboxes containing goods. For example, when a grocer receives a box ofcrackers, raisins, or other articles whose contents he wishes todisplay, and at the same time to protect from dust, also from thieves,and yet render them accessible for the purpose of removal of a portionto supply customers, the top of the box may be removed and my detachablefront or cover applied to the same. In such case the box may be turnedon its side, so as to better display the goods.

By use of myimprovement the dealer avoids the necessity of placing thegoods in separate boxes for the purpose of exposing and yet protectingthe goods.

In practice the dealer will keep on hand a number of the detachable boxfronts or cov' ers, and will transfer them from one set of boxes toanother as occasion requires.

The invention consists in the specific construction of the device, ashereinafter described and claimed.

By referring to the drawing, A represents a sash of any suitable size,which slides vertically in a grooved guide-frame, B, that is attached byscrews, hooks and eyes, or otherwise, to the show-case, shelf, or box inwhich the goods are stored.

The guide-frame B rests, by a projecting top piece, a, on the box orother article, which top piece, however, is not necessarily required forall purposes.

The sash A is retained at any suitable position by suitablefriction-springs b applied to the guide-tongues,which friction-sprin gsserve, also, for locking the sash in closed position by throwing a lipor shoulder at the upper part of the sash-frame over the top part of theguide-frame B.

The sash A is prevented from dropping out of the guide-frame byspring-bolts 0, that pass through the sides of the guide-frame intorecesses or notches of the sashl'rame.

By withdrawing the spring-bolts the sash may be readily removed from theguide-frame. By unscrewing the fastening-screws or detaching the booksthe guide-frame may be readily removed and attached to any other case orbox until the same is empty, and so on, the sash forming a protectionfor the contents of the show-case, box, or other object to which it isapplied.

.5, For opening the sash, the hands are placed on the top of the box orcase, and the forefingers pressed on the sashuntil the lip of the sameclears the guide-frame and admits the sliding down of the sash, the lipand frictionsprings holding the sash at any suitable position.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The frame B, provided with side grooves and the toppiece or lip on, the spring-stops 0, and the adjustable or sliding sashA, having side notches, as shown and described, the whole forming adevice applicable as a detachable protector and transparent front orcover for boxes containing goods to be exhibited and sold, as specified.
